Many people think Obama is the greatest president ever. What could possibly make him more awesome? He is a time traveller.
How else can you explain the fact that he gets his own daughter's age wrong and doesn't know when his birthday is, even though a party is being planned right now? Time travelers can have great difficulty keeping track of what day it is.
Why else do you think he says "uh" all the time when he is not on a teleprompter? He is avoiding tainting of the time line by keeping future knowledge secret.
He may have hurt unenployment, the used car market, health care, and more, but the space time continuum is in tact. And for that President Obama, I thank you.
